Abstract

The class of two-dimensional (2D) materials and their nanostructured derivatives (e.g. heterostructures and nanocomposites) are considered promising for photonic devices for sensing devices, mainly because they present, in general, fast charge transfer kinetics, high surface area, easy functionalization and wide range of optical properties. In the face of the COVID-19 pandemic we are experiencing, these materials become deeply attractive for the development of nanobiosensors, potentially capable of detecting the most diverse pathogens - such as SARS-CoV-2 - in a simple, fast and sensitive way. With this application in mind, the present project aims at the synthesis of different materials based on graphene derivatives, graphitic carbon nitride, transition metal dichalcogenides and monochalcogenides of IV-VI groups, in their lamellar and 2D form, and heterostructures and nanocomposites based on these materials. The samples will be produced with controlled architecture (i.e. morphology, number of layers, layer size) and evaluated for their optical properties. The sensitivity of the materials that prove to be promising will be investigated based on a complex model (Biotin-Streptavidin), aiming at the optimization of the system for biosensing by optical phenomena: surface enhanced Raman spectroscopy and luminescence. Finally, we expect to contribute to the rational development of materials suitable for ultra-sensitive sensing, capable of reaching future practical applications.
